WebThis pathway is not available to aldehydes and ketones, but it dominates the reaction of carboxylic acid derivatives. The overall result is that when an amine (or any nucleophile) reacts with a carboxylic acid derivative the outcome is that the amine replaces the leaving group (a hydrogen is lost from the amine nitrogen too). WebSpecifically, aldehydes become aldimines, and ketones become ketimines. In the case of formaldehyde (R’ = H), the imine products are typically cyclic trimers.
